Published Hotter than infinity: Light pulses can behave like an exotic gas
(via sciencedaily.com) In our modern society huge amounts of data are transmitted every day, mainly as short optical pulses propagating through glass fibers. With the steadily increasing density of such optical signals, their interaction grows, which can lead to data loss. Physicists are now investigating how to control large numbers of optical pulses as precisely as possible to reduce the effect of such interactions. To this end they have monitored an ensemble of optical pulses as they propagated through an optical fiber and have found that it follows fixed rules -- albeit mainly those of thermodynamics.
Published Ringing an electronic wave: Elusive massive phason observed in a charge density wave
(via sciencedaily.com) Researchers have detected the existence of a charge density wave of electrons that acquires mass as it interacts with the background lattice ions of the material over long distances.
Published Colloids get creative to pave the way for next generation photonics
(via sciencedaily.com) Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.

(via sciencedaily.com) Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
Published Two-dimensional quantum freeze
(via sciencedaily.com) Researchers have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.

Published The positive outlooks of studying negatively-charged chiral molecules
(via sciencedaily.com) The ability to distinguish two chiral enantiomers is an essential analytical capability for chemical industries including pharmaceutical companies, flavor/odor engineering and forensic science. A new wave of chiral optical methods have shown significant improvements in chiral sensitivity, compared to their predecessors, leading to potential analytical advantages for chiral discrimination.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Researchers propose a simple, inexpensive approach to fabricating carbon nanotube wiring on plastic films
(via sciencedaily.com) Researchers have developed an inexpensive method for fabricating multi-walled carbon nanotubes (MWNTs) on a plastic film. The proposed method is simple, can be applied under ambient conditions, reuses MWNTs, and produces flexible wires of tunable resistances without requiring additional steps. It eliminates several drawbacks of current fabrication methods, making it useful for large-scale manufacturing of carbon wiring for flexible all-carbon devices.
Published A motion freezer for many particles
(via sciencedaily.com) From the way that particles scatter light, it is possible to calculate a special light field that can slow these particles down. This is a new and powerful method to cool particles down to extremely low temperatures.

Published Let there be (controlled) light
(via sciencedaily.com) In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.
Published The quantum twisting microscope: A new lens on quantum materials
(via sciencedaily.com) One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.
